IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 102,131, dated April 19,1870.

To all whom it may concern:

.Be it known that I, WILLIAM A. KIRBY, of the city of Auburn, in the county of Cayuga and State of New York, have invented a certain new and useful Improvement in Harvesting-Machines, of which the following is a specification Figure 1 represents a perspective view of that portion of the harvester to which the invention relatos. Fig. 3 represents an elevation of the same parts shown in Fig. 1. Fig. 2 is a plan view of portions of the same parts. Fig. 4 is a plan view of the improvement claimed, with parts immediately connected therewith. Fig. 5 is a sectional view of the same parts represented by Fig. 4.

Similar letters of reference, where they occur in the separate figures, denote like parts of the machine in all the drawings.

My invention consists in providing a slide and attaching the same to the pvot connecting the two parts of the pitman, and in providing a guideway to receive and hold the same, and control the lateral movement and vertical position thereof.

It is not deemed necessary to particularly describe those parts of the harvester not di rectly connected with the improvement intended to be patented, inasmuch as said improvement may be applied to all the variouslyarranged machines used as harvesters which have a jointed or hinged cutter-bar.

To enable others skilled in the art to make and use my invention, I will proceed to de all times in the direct line of motion between said wrist and the end of the pitman which is pivoted to the cutters.

The guideway F is attached to, or may be cast with and as a part of, the main frame, and is so located as to range lengthwise in line with the motion of the pitman. It is made of sufficient Width and depth to receive and hold the slide R below the flanges upon the sides thereof, and of a length corresponding with the distance traversed by the pivoted part of the pitman, and is made open at both ends.

The advantage of this guideway F is, that it sustains the two parts of the pitman-connections at all times in line, and in the direct line of motion of those parts and it also holds the pivoted endswhere the two portions of the pitman meet, at all times in the same position verticallyin regard to the main frame.

The advantage of this arrangement of the pitman-oonnection is, that the finger-bar and its appliances (the cutters) may be raised and folded up, and again lowered to the ground, without disconnectin g any of the gearin g; and when the cutter-bar is raised to a position a little beyond a right angle, and so as to lean toward the main frame sufficiently so as not to fall back upon the ground, although the gearing and the main part ot the pitman N continue their motions, yet the cutters when in that position have no motion, as it is all taken up in the two hinged pitmen N and G.

Having thus fully described my invention, and the operation thereof, what I claim therein as new, and desire to secure by Letters Patent, is

The guideway F, slide R, hinged pitman N 0 uniting the crank-shaft and cutter-bar, combined and arran god substantially as described.
